Mental illness such as depression and anxiety as well as cerebrovascular disease are
linked to impairment of neurocardiac function mediated by changes to the autonomic …

Abstract Systems theory has long been used in psychology, biology, and sociology. This
paper applies newer methods of control systems modeling for assessing system stability in …

In recent years there has been substantial support for heart rate variability biofeedback
(HRVB) as a treatment for a variety of disorders and for performance enhancement. Since …

Heart rate variability biofeedback (HRVB) significantly improves heart rate variability (HRV).
Breathing at resonance frequency (RF, approximately 6 breaths/min) constitutes a key part …

Heart rate variability biofeedback is known to have multiple effects on the cardiovascular
system, the respiratory system, and emotional reactivity. This paper reviews the origins of …

Perception and cognition are modulated by the phase of the cardiac signal in which the
stimuli are presented. This has been shown by locking the presentation of stimuli to distinct …

Interoception, the ability to perceive internal bodily sensations, and heart rate variability
(HRV) share common physiological pathways, including the baroreflex feedback loop. The …

We know surprisingly little on how heartbeat-evoked responses (HERs) vary with cardiac
parameters. Here, we measured both stroke volume, or volume of blood ejected at each …

The evaluation of propensity to postural syncope necessitates the concomitant
characterization of the cardiovascular and cerebrovascular controls and a method capable …

Interoceptive processes emanating from baroreceptor signals support emotional functioning.
Previous research suggests a unique link to fear: fearful faces, presented in synchrony with …
